- useful Improvements inCombinatioii Tractors and Plows, of which thefollowing is a specification.

'.lliisv invention relates to a combination tractor and plow, being amachine, implement or vehicle driven by an engine and adapted for theuse of farmers for plowing or drawing heavy loads, and to be of a plainor simple construction so that it may be inaiuifactured at a moderateexpense, comparatively.

The invention which may be mounted en-d-to-end upon a single shaft oraxle, said wheels being rotatable to propel the vehicle, and theirrotation as compared with each other, being permitted to be at differentdegrees of speed so that the vehicle may be moved at right angles oracute angles from a'direct line of travel, and will admit moving uponlong curves, short curves or forwardly, these features beingparticularly useful when the implement is used for plowing, to turn atthe end of a furrow, when moving on paral lel lines in the plowing of afield.

The invention includes the use of spadercylinders or traction wheelsprovided with pawls and ratchets so arranged that one wheel which ispositively rotated, may cause an adjacent wheel to be rotated in thesame direction and at the same speed, and will also provide for arearward movement, at a lesser degree of speed, of one wheel than the 1rearward movement of the wheel which is positively rotated and withwhich it is connected, these features beingquite necessary when themachine is used for plowing, in order to turn directly about at the endof a field when forming parallel furrows.

The invention also discloses a convenient means for changing the speedof the wheels without changing the rotatable movement of the engineshaft; the use of dust-guards between the wheels found useful toprotectthe bearingsof said Wheels; the use of a resiliently mounted comb forcleaning the plow teeth; permanent friction-lugs upon theperipli'eriesof the wheels for the use or" the implement as tractor andproviding has especial reference to theemployment of a plurality oftraction wheelsremovable mountings for the plow teethwhen used as aplow; convenient means under control of an operator for steering, andthe employment of means for positive 7; driving the end-wheels of theseries of traction wheels at diflerent-degrees of speed.

The invention consists of the novel con struction, combination andarrangement or parts as described herein and claimed, and as illustratedin the drawing, it being on derstood that changes in form, size,proportion and minor details may be made within the scopeot the claimswithoutdepar from the spirit of the invention or saer .c-- ing any ofits advantages. In the drawing, Figure 1; is ia ti gi broken, plan viewofa combination tractor and plow enibodyingv my invention. his. 53

Fig. 9 is anenlarged detail, partly broken, to clearly show con s notion of twoconnected wheels. l 10 is a sectional View on.line a a of Fig. 3. Figs.11; and 12 are side and front views, respectively, or curved plow-teethor, harrowteeth. l3 and it are side and views, respectively, ofstraigl'it plowd et or harrow-teeth Referring now to the drawing; for,i'nore particular-description, numeral 1 indi a frame, preferably oirectangular town, and of any suitable length and width; 2 preferably itis formed with a tapered or convergent front part, but this notport-ant. The frame may be provided suitable cross-bars for the supportthereon of aireiigine 2, and a plattoi'm 3 upon which may be supported aradiator 4i and a gaso lone-tank 5.

Disposed transversely oi? the vehicle and having suitable bearings uponthe side members of the frame, is the shaft or axle 6; and

mounted to rotate thereon are a plurality ofwheels adapted for use astraction-members or for rotary plow-members, and for convenience, theyare indicated at 7, 8, 9 and 10. The length of the axle will depend uponthe width of the wheel tires or the number of Wheels to be mountedthereon. While 1 19 have shown four of these wheels, a. greater orlessernumber may be employed as may be desired. I

As best shown in Fig. 8 each wheel is provided at its ends with acircular web 11 5 having at its middle a hub or sleeve 12 for a bearingupon the axle. Secured in any suitable manner upon the outer ends ofwheels 7 and 10, and having a uniform diameter, are sprocket wheels 13,and having'a less diameter and secured outwardly of Wheels 13 aresprocket wheels 14, these sprocket wheels having a sleeve 15 forbearings upon the axle. Washers or spacingmembers 16- are also providedand are dispo'sedbetween the ends of the adjacent wheels, to prevent acontact of one wheel tire with another.

Between each of the wheels is provided a dust-guard 17 best shown inFig. 9, each so consisting of a circular rimlS of less diameter whichmay be secured upon a web of one of the wheels, said rim having anannular, transverse flange 19 extending toward the web-of an adjacentwheel and provided with as an outwardly projecting terminal rim 20; iand soil, pebbles or the like, which may be carried upwardly by thewheels when plowing, or when used as a tractor, and which may passbetween the tires of the wheels, so. will. be caught upon these guards,and the bearings of the wheels npon the axle will therefore beprotected.

Means are provided and now tobe described for causing a rotatablemovement of wheels 7 and 10 at uniform or different degrees of speed.The engine shaft is indicated at 21. At 22 is indicated an interme diateshaft; and at23 and 23, disposed in alinement, are indicated operatingshafts, all so of said shafts being disposed parallel with the axle.

A clutch is provided to-operate between the engine shaft and shaft Theoperating pinion of the engine shaft is indicated at 24. Shaft 22 "isprovided'with a pinion 25; between these pinions, in suitable bearingsand disposed at right angles to these shafts, is a shaft 26 upon whichis mounted I the two adjacent pinions 27 and 28. A hand-lever isindicated at 29, and. by use of this lever, shaft 26 may have aslidingmovement tocause engagement of either one of pinions 27 or 28,asmay be desired, with the pinion ofthe engineshaft and with the pin- 8%?ion of shaft 22. for causing its rotation.

Shaft 22 is provided with the sprocket.

33 are of the same diameter, ascompared with each other, and of lessdiameter than wheels 34.. They are disposed in alinement with thesprocket wheels of greater-diameter of traction wheels 7 and 10; andsprocket wheels Mare disposed in alinement with the sprocket wheels oflesser diameter of said traction wheels.

At 35 are indicated sprocket chains adapted to cause a rotation oftract-ion wheels 7 and 10, by the rotation of shafts 23 and 23, thesechains extending betweenand connecting sprocket wheels 33 with sprocketwheels 13; and it will be understoodthat if chains 35 are removed, andif sprocket wheels 34 and 1 are connected by sprocket chains (notshown), the comparative degree of speed for traction wheels 7 and 10will be decreased without changing the speed of the engine. This changeof speed is often, desirable. During operation, when'plow teeth ofconsiderable length are employed, it is obvious that the resistance totheir swinging movements while embedded in the ground is greater thanwhen shorter teeth are used,.

and at this time the vehicle should move slower. This may beaccomplished without changing the speed of the engine if chain connectssprocket wheels 13 and 33, as shown in Fig. 1. Alsoif the ground is hardor compact, the wheels 7, 8, 9 and 10 should have a less degree ofrotation than when plowing in light soil. When the device is used as atractor, a greater speed may be desired, and for this purpose, withoutchanging the speed of the engine, sprocket chain 35 may be removed, andby use of sprocket chains each of sprocket wheels 14% may be connectedwith a sprocket wheel 34, with the result that wheels 7 to 10 inclusivewill have,

comparatively, a greater degree of rotation.

As best shown in Fig. 10 an internal circular rack 36 may be employedfor the traction wheels. When a series of four traction wheels areemployed, illustrated in the drawings, an internal 'rack 36 is providedfor wheels 8 and 9, these wheels being mounted as idlers upon shaft 6.At 37 are indicated pawls adapted Ito normally. en-

gage the teeth of the racks, the pawls being pivotally mounted uponprojections or bosses 38 having mountings upon the driven wheels 7 and10. By this arrangement, a

forward rotatable movement of wheels 7 and 10 will cause wheels 8 and 9tohave a likerotatablo movement and at the same degree of speed as saidwheels 7 and 10.- In

the operation of plowing where all of the furrows are formed parallel,it is desirable and to nausea uni/lemon: of the tractor upon a shar'g')curve, andlin describing this mover cut the outer wheel, as forii'istance wheel l l more forwardly and the inner wheel w morerearwardly, and on account of the operation of the ratchet and pawl, asdescribed, wheel 8 in its rearward movement will not move at the samedegree of speed the driven wheel with which it is connected, andtherefore the operation of moving upon short curvcsis facilitated. And

if the machine is moved to describe a short. curve in the oppositedirection to that de scribed the parts operate with the same eflect oradvantage.

While I have described and prefer to employ the-pavvls andratchetsui'ientioned, I do notlimit. myself in this respect, for aplurality of wheel members provided with rotatable means and mountedupon a single shaft, whether we as tractor or as a u plow, has manyadvantages, as" cotnparcd with a single wheel, for these purposes.

At 39 are indicated friction lugs, and preferably they are disposedtipomeach tire in rows diagonal to the long tudinal axis of the wheeland nently thereon, said lugs also forming rows which are COi'ltlllUOUsand disposed at right angles to said longitudinal axis of the Wheel.

The friction lugs may be of any desired size oiflproportimi required toprevent skidding of the wheels, when the implement is used as a tractor.The lugs may be provided with longitudinal apertures 40; and when theyare mounted upon the tires, the apertures 4:0 extend in the directionand may conform to the curvature of thetires.

4-1., and l3ar-e indicated teeth which may be employed, all havingangular terminals, bases or holde1-'-1nembers 44 of uniform size andshape for insertion within apertures 40 of the lugs. Teeth ll havecurved body-portions, while the body-portions of teeth 1 55 arestraight. Teeth 43 are particularly useful for plowing to a considerabledepth where the soil is loose (i1- sandyyand are useful in the practiceof dry farming or thentilixation of land in localities where the soil ismmzparatively dry, the transverse lo: a of these teeth temling to movethe sub-soil upwardly to advantage.

in. operation, the teeth enter tie ground with co npar iv ely a slightresistance atthe front oi the wheels, and the soil is thrown upwardly atthe rear. Each angular terminal or holder 44-, since it is disposedforwardly the tooth body, provides a strong construction for resistinthe strain imposed upon thetooth at the time it moves ardly at the rearof the wheels, and the n cc-ion-men'ibers )rovide a strong holding quitenecessary, at the end of the field secured i'iyidlydor. permameans forthe mounting of the teeth. At 46 are indicated set-screws. The angularholder 4-4: of each tooth provided with a rearward projection or heel47. By means of the setscrews traversing these projec:

tions, the teeth, or atiy'of them, maybe reniovably secured to'tllelugsyand in practice, the teeth may be conveniently removed from thelugs when it is desired to'use the im plement as a tractor.

Any convenient means may be employed for steering. Preferably I employthe single front wheel 48, best shown in Fig. 6. At.

49 isin dicated a cylindrical plate or support provided at its middlewith a king pin 50 for a seating, vertically, in an aperture (not shown)formed in-the front end of the machine .frame; and mounted upon thelower end of pin 50 is a spring 51.

- Mounted upon the cylindrical supportingplate 49 is the sleeve or hn'52 of wheel 48, and the wheel may therefore freely rotate, the bearingsfor its hub or sleeve beingthe cylindrical support 49. If a lateralswinging movement is provided for support 49, the wheel may have acorresponding movement.

Rigidly mounted upon the lower part of the cylindrical supporting-plateis the segmental rack At 54- and 55am indicated brackets disposed belowand mounted upon the frame toprovide bearings for a shaft 56. Bracket54: provides a mounting for a vertical stub-shaft 57 upon which ismounted a spool pinion 58 for engagement with the segmental rack, andupon the terminal of shaft 56 is mounted a miter gear 59 for en gagementwith a miter gear 60 formed upon (the upper end of pinion 58.

At. 61 is indicated a steering shaft, and under control of the operatorthe machine maybe guided in. a Well known manner,

gear (32 .of shaft (31 being in engagementwith a of shaft 56. And whenmoving over obstructions or uneven surfaces, the spring 51 will tend toprevent vibrations.

When using the machine for plowing fields of stubble or when working indamp ground, the soil, or grass-recs may be carried upi'ardly upon theplow-teeth, and-in order, that the teeth may become free from theseobstructions and may be cleaned, I provide the cleaning device orp'ulveriz'er G4 best'shown in vl igs. l and 7.

The cleaner or pulverizcr consistsof a. plate (55 disposed parallel\viththe axle ru wardl y of the traction wheels, said plate havingpivots G6 on its ends mounted in brackets (37, these brackets beingmounted upon and,

preferably disposed below the frame; The p.ate is pro ed withforwardly-projecting teeth 68 ada red to engage between the continuousrows of teeth of the traction wheels,

and preferably the teeth are; inclined upwardly from plate 65. Thisplate and teeth operating in a practical way to dislodge obstructions oradhesions from the teeth as they move upwardly. To prevent breakage ofthe teeth incident to their use when large obstructions are encountered,spiral springs 69 are provided, the upper and lower ends of saidsprings, respectively, bearing upon bgackets 67 and upon the plate nearits front e ge.

rear edge with upright arms or braces 70 adapted, normally, to bear uponthe lower side of the machine frame, on account of the downward pressureof the springs upon the plate. When a large obstruction is carriedupwardly upon the teeth, springs 69 operate to resist, with aconsiderable force, an upward swinging movement of the comb or cleaner,but the force of the springs being overcome, they may be compressed toallow the obstruction to pass upwardly.

Numerals 71 indicate staples or holders secured upon the rear end of theframe for securing thereto any heavy object to be drawn, and numeral 72indicates a pulley mounted upon the free end of shaft 22, this pulleybeing useful for many purposes, when the implement is used stationary,and after sprocket chain 32 has been removed.

It may be stated that the series of wheels disposed end-to-end provide atractor of greater width than could conveniently be provided by anyother construction, this feature being of advantage while passing oversoft ground or wet soil. The parts may therefore have a light weight,comparatively,

and still provide the required frictional recovers.
